BED-SPRING- CONSTRUCTION.

Applcation filed November 4, 1922. Serial No. 598,991.

My invention pertains to structural novelties in bedsprings and relates more particularly to the means for mounting or supporting the bedspring on the bedstead and in the manner of attaching or anchoring the lower ends of the upright, spiral springs tothe frame of the structure.

One purpose of the invention is the production of a bedspring appliance equipped with simple and effective positive-locking means for mounting it with facility and dispatch on bedsteads having different distances between their side-rails which constitute the support-ing means for the bedspring proper.

This novel structural feature enables the improved bedspring to be employed on all usual bedsteads regardless of whether they are made of wood or metal and it compensates or cares for the diEerenc-es in the transverse dimensions of such bedsteads.

Another aim or purpose of the invention is to provide va simple, inexpensive, and elticient fastening or means of attachment for the lower ends of the upstanding, spiral springs composing the major portion or cushion structure of the bedspring.

To the attainment of these and other desirable ends, I have devised the desirable and preferred .embodiment of the invention illustrated in the accompanying drawing forming a part of this specification and throughout the several views of which the same reference characters have been used to designate like parts or elements.

In this drawing:--

Figure 1 is a fragmentary, horizontal section through a side portion of the bedspring above its frame structure;

Figure 2 is an enlarged, vertical cross-section through the side or marginal portion of the appliance;

Figure 8 is a fragmentary, sectional detail showing the manner of securing one of the bed-spring brackets on the frame; and

Figures 4, 5, 6 and 7 show the manner of mounting the spiral-springs.

Referring to this drawing, it will be per-Y ceived that the new and improved bedspring structure. includes a suitable frame having a dat, edgewise-disposed, horizontal, longitudinal, side bar 10 to which a number of sheetmetal brackets 11 and the laterally bent ends 12 of a plurality of deformed, spring-supporting cross-bars 18 are riveted at intervals.

Each such bracket, which supports one of the border spiral-springs, has a vertical wall 14, having an upright, narrow slot 15, and an inwardly-extended, horizontal, top wall 16, the section 14 having inturned stittening and strengthening flanges 17, 17 along its two vertical margins, the part 16 having lface of the wall 14 of the bracket, the three parts 10, 14 and 12 being held firmly and tixedly together by a rivet 20 extended through registering or aligned holes in the three members.

Two or more of these spaced, slotted brackets accommodate in their elongated openings 15 a corresponding number (in the present instance three) of arms' 21, laterally bent ears 22 at the outer ends of which are riveted to the depending fia-nge of a horizontal angle-bar 28, the other outstanding flange of which is adapted to rest on the angle side-bar or similar side-rail 24 of the bedstead.

The inner end of each such element 21 has a bent terminal ear 25 notched in its lower end at 26 to fit over the top of the corresponding cross-bar 18, whereas the upper edge of each of such members 21 has a plurality or series of notches or recesses 27 any one of which, according to the adjustment, is designed and intended to receive that part of the wall 14 of the bracket directly above or forming the top margin of the slot 15. y Thus the supporting bar 28 may be adjustably positioned various distances from the frame bar 10 as may be required for different widths of bedsteads, whereby under all circumstances the element 28 may be brought to rest on the bedstead side-rail 24.

The weight of the bedspring is borne by the plurality of bars or arms 2l which are locked in position by the interfitting of those parts of the brackets above their slots engaging the corresponding notches or cavities,

top edge ofthe its upper and lower faces leading to said aperture, and an upright spiral-spring mounted on said bracket and having a convolution accommodated in said arcuate groove and aperture and a straight terminal portion at its lower end bearing against a portion of said bracket to prevent unintentional unscrewing and removal of the spring.

4. ln a bed-spring` structure of the character described, the combination of a bedspring` frame, a slotted bracket mounted thereon7 an outstanding` frame-supporting bar slidingly adjustable in said slot7 and an upright spiral-spring mounted on said bracket.

5. In a bed-spring structure of the character described, the combination of a bedspring,- frame having a side-bar, a slotted sheet-metal bracket secured to said side-bar and having lugs struck out of its body over lying and bearing on the top of said sidebar, an outstanding frame-supporting bar slidingly adjustable in said slot, and an upright spiral-spring mounted on said bracket.

In witness whereof I have hereunto set my hand.

BEN K. FORD.
